Discovery 4 Xs 2010
Discussion
Good evening.
I bought a discovery 4 yesterday and.... In true discovery fashion I got 2 miles before the 1st issue.
I've got a suspension fault. I don't want to go back to the owner as it was a private sale, plus I got it at a good price for the condition. Also they are earlderly & I don't think they would have known of the issues.
I'm looking for help to diagnose the fault as I'm around 3 hours from the closest LR dealership.
So I started to drive, then a warning in orange 'suspension fault' appeared on the dash, followed by 'normal ride height only' then 'reduce speed to 30 MPH' then the suspension dropped onto the stops.
Today I was having a tinker & then very randomly the suspension would rises to 'off road height' for a few miles then the same issues flag up again.
The compressor, which is the updated AMK which has a date stamped of 2013, seems to run for no more than 10 seconds. It doesnt seem to pressurise though as I took the pipe off & it doesn't leak out & on the other end it doesn't create a suction.
I suspect it to be the compressor but I can't be sure as the time the suspension up I had the pipes disconnected to the compressor, so therefore I assume it used it tank of air but what's causing it to go down while driving? So sound of leaks either time. I had the window open both times & no radio on as I was checking for any issues both time.
I'm happy to buy a new compressor but don't want if it's not needed, obviously.
I've got a health check on Thursday for my additional warranty & my cambelt is booked in for a weeks time so need to get the issue(s) sorted ASAP.
Cheers!

Without the codes read.
You could lob parts at random with no success.
It could be the compressor.
Or it could be one of the 4 sensors.
Given the compressor runs for 10 seconds then stops.
I’m not sure to point the blame at that just yet.
Lift it from Normal to Off road then access and back a few times.
Try doing that with door closed, window down and leaning in to flick switch.
Watch the front and backs, the rear rises quicker but if the front is clearly struggling then it may be a front valve block.
The compressor should run for 30 seconds or so then turn off. If it runs longer than that then it could be tired.
Check each height sensor and the wiring going into them.
Not the first time a chaffed wire has caused a fault.
But ultimately, the codes give the answer.
Make sure the code reader is a good one. Cheap ones can’t read all the codes so aren’t worth it.

Possibly slightly different but may help.
2016 Discovery 4 on 50k and I had the same warning light come on occasionally although it did maintain normal height.
I had noticed that it seemed to happen more when it was wet.
Being a bit stupid I ordered a new suspension compressor from Aerosus (I think)
Should have got under the car and had a look for the simple things first.
I found that some of the wires to the compressor had worn through.
The new compressor came with this part of the wiring so I went ahead and fitted it and the new compressor.
It is a bit awkward as the original looks like it is probably fitted to the chassis before the body.
I struggled to get the new plastic sound deadening box fitted to used the old one.
As my dad used to tell me - A fool and his money are easy parted.

Get yourself an GAP iid obd reader. It will pay for itself very quickly if you plan to do your own maintenance. You can pick them up second hand but you have to pay to get them transferred to your VIN so bear that in mind.
Bluetooth versions are easier to use but the older versions still do what you need to do.
